I've been looking for a program to enable A2DP on my PPC quickly and so far this is the closest I've come. I don't think it enables A2DP but opens a mono bluetooth gateway.
It's very quick and works every time without skips. However it has very poor "phone call" level quality. If I go through the typical hassle of enabling A2DP from the bluetooth settings then it works about 50 percent of the time (other 50 percent it skips constantly) but I get pretty high quality stereo sound.
I'm still looking for a way to open the A2DP profile or whatever it's called.
The headphones can't open the profile... or they can, but if they do I just get skips.
